TO'o ZZ whom it may concern I Be it known that I, FREDERICK SEABERG, .1acitizen f the United States, and resident of Chicago, in the county ofCook and f5 State'of Illinois, have invented certain new and usefulImprovements in Door-OperatingMechanism for Railway-Cars, of-which thefollowing is a description, reference be- .l ing had to the accompanyingdrawings, I

I0 which form apart of my specification."

'My invention relates to door operating mechanism that is moreespecially adapted for use'in connection with the hopper-bot; 1 {tomtype of cars, wherein the doors form a. part ofthe hopper and openthrough the i 2 vat'ionof a portion of a du'mp car provided with. myimproved door operating mechanism; the doors being shown closed. Fig. isacross sectional ,view taken on line 2-2 of Fig. 1; Fig. 3 is a crosssectional view taken on line 33 of Fig. 2, looking down, 'with thedoorsjshown dropped or open.

jfjFigfl isa detail view'of a portion of the ffoperating mechanism,whereby the locking "'or holding portion of the door operating positionI fjMyf'""vention is-shown in Fig. 1 applied to that class of dump carswhich are pro- "vided with 'a dumping-hopper bottom ari ranged'longitudinally of the car of which the clumping-v doors form apart: thedoors when closcdforming a V shaped hopper bottom "in cross section. Thedoors extend longitudinally of the car between the trucks and constitutewhat may be termed two swinging dumping sections 1 and 2. at oppositesides of the longitudinal center of the car. The doors" 1 and'2 aresuitably pivoted at 3, to the frame or. longitudinal sills of the 30 carin a well known manner. Rotatably mounted in suitable lugs on the doorfor example, is a shaft 4. which extends longimechanism is acthated wheninthe lockin'g y tudinallyof the door, or doors,"to the other 'end of'the dumping section, and is there provided with. if des1red,-sim1larmechanism to that now to be described. The shaft 4 is provided at itsend with the link or arm 5, which is secured to the shaft so as torotate or move therewith. Pivotally secured to the free or outer end ofthe link orarm 5 is a 0 connecting link or bar 6. The other end of thislink 6 is pivotally secured to door 1, or

preferably to a lug or bracket 7 secured on the Outer or under side ofthe door, as clearly shown in Fig. 2. The connecting bar or link 6 ispreferably composed of two members spread apart, as seen in Fig. 3, oritmay be bifurcated and has a sheave S mounted between the bifurcations,preferably at a point near the pivotal connectionof the bar with thedoor 1. With the arm or link 5 secured between the bifurcations of link6, as shown in Fig. 3, it is of course necessary to how the connectingbar or link 6 at or near its center as shown. so as to permit the axesof l the respective pivotal points to occupy substantially the samehorizontal plane as indicated in Fig. 2. The arm or link-3 is so securedon shaft 4, that it will extend out in a horizontal direction when thedoors are So completely closed; and by having the arm or link 5 pivotedbetween the bifurcations shown in Fig. 2, that is, with their ends iiithe same horizontal plane, or at a deadcenter as it were, the doors willbe securely locked in closed position. v

Suitably mounted in the plates or brat-k ets 9 and extendingtransversely of the car at the end of the dumping sections. is jarotatable shaft'lO, whose outer ends may be provided with any suitableoperating device, as for example the hand wheels 11. Secured to saidshaft 1.0. and to bc wound about it. is the flexible connection or chain12. This chain 12 takes beneath sheave 3 mounted on connecting bar 6.and is secured atits other end to the link or arm 5, see Fig. 2. Inorder to provide a suitable bearing. for the chain 12 and maintain it inplace, the end of arm 5 where it is secured to shaft' 1 maybe providedvwith a groove at 1 -3, 105 see Fig. or any other suitable method may beemployed to receive and maintain the chain against lateral displacement.

From the description heretofore given, it is evident that when the doorsare open,

'0 in the proper direcup on it. As the h chain is secured to arm or andthe point of connecr and sh'aii't {l and then h shears 8, the pull ofthe arm or lifills'. 5 upward from m wn in dot-ted lines in Fig. 2,
